This is a "live" recording of a qrq iCW NET that took place over the internet on 1-22-2011.
There were 6 iCW ops in attendance. We use various means to send qrq cw audio tones to our computer soundcard inputs in order to send full duplex, high fidelity morse code audio tones over the internet to each other using the mumble voice chat program. All software is free.
